How MS Burns my time

I have an index.cshtml page with only 1 line of code.

*iframe src="~/Viewer/viewer.html?file=/Home/IndexAsPDF&page-height=1"**/iframe*


[Sorry, had to replace the gt and lt with * because wordpress is also a POS when it comes to displaying code.]

So what does visual studio do when I try to edit the URL? CRASH! WTF! MS, don’t you test this $800 POS?
